CB-1141 Threaded Hydraulic Quick Coupling – 316 Stainless + Brass Hybrid for High-Pressure Jacks
The CB-1141 quick coupler is designed for portable hydraulic jacks and high-pressure lifting systems. Featuring a 316 stainless steel body and a brass locking sleeve, it combines corrosion resistance with wear protection. The threaded locking mechanism ensures secure connections even in vibration-heavy environments, while the compact mating seal minimizes separation forces—allowing connection and disconnection under residual pressure up to 5000 PSI.
